The invention relates to compounds of formula (I). ##STR1## wherein R.sub.1 represents a hydrogen atom or a C.sub.1-10 alkyl, C.sub.3-7 cycloalkyl, C.sub.3-6 alkenyl, C.sub.3-7 cycloalkyl-(C.sub.1-4) alkyl, C.sub.3-10 alkynyl, phenyl or phenyl-C.sub.1-3 alkyl group, and one of the groups represented by R.sup.2, R.sup.3 and R.sup.4 is a hydrogen atom or a C.sub.1-6 alkyl, C.sub.3-7 cycloalkyl, C.sub.2-6 alkenyl or phenyl-(C.sub.1-3) alkyl group and each of the other two groups, which may be the same or different, represents a hydrogen atom or a C.sub.1-6 alkyl group; and physiologically acceptable salts and solvates, e.g. hydrates thereof. The compounds are potent selective antagonists at "neuronal" 5-hydroxytryptamine receptors and are useful in the treatment of migraine and psychotic disorders such as schizophrenia.
该发明涉及式(I)的化合物。其中R₁代表氢原子或C₁-₁₀烷基,C₃-₇环烷基,C₃-₆烯基,C₃-₇环烷基-(C₁-₄)烷基,C₃-₁₀炔基,苯基或苯基-C₁-₃烷基基团,而由R²、R³和R⁴代表的基团中的一个是氢原子或C₁-₆烷基,C₃-₇环烷基,C₂-₆烯基或苯基-(C₁-₃)烷基基团,另外两个基团,可以相同也可以不同,代表氢原子或C₁-₆烷基基团;以及生理上可接受的盐和溶剂化合物,例如其水合物。这些化合物是“神经元”5-羟色胺受体的有效选择性拮抗剂,并可用于治疗偏头痛和精神分裂症等精神障碍。
